A.C.E. Mod is a full conversion modification for Bohemia Interactive's ArmA 2 Operation Arrowhead.

Our primary mission is to create a wide variety of real world weapons, vehicles, equipment, and tactics so that those playing the ACE modification will be able to better simulate combined arms combat on a modern battlefield.

ACE is designed from the bottom up with the goal of encouraging its users to employ real world tactics and strategy (fighting as a team) in order to accomplish realistic military objectives. We strive to create hyper-realism without losing sight that the mod must be playable by the “advanced” user. Our focus is not only on creating features and models which highlight realism but also on supporting the creation of realistic missions in which one may experience the full spectrum of virtual combat.
